Uses
Uses & Benefits
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
  
  • Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
